Title:
COMPOUND OXIDE SOL AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3729205
Kind Code:
B2
Abstract:
PURPOSE: To obtain a compound oxide sol having high specific surface area of dispersed fine particles and a great number of pores in the interior.
CONSTITUTION: A sol comprising dispersed fine particles of a compound oxide composed of silica and an inorganic oxide except silica. An average particle diameter (Dp) and a specific surface area (S) of the fine particles satisfy the inequality S(m2/g)≥3,000/Dp (nm). The sol is produced by forming colloidal particles in an aqueous solution of an alkali having pH ≥10 or seed particle dispersion having PH ≥10 without controlling pH.
